"Avatar" director James Cameron had some nasty words for Glenn Beck and global warming "deniers" yesterday.

Cameron said at a news conference that he would like to shoot "those boneheads," referring to skeptics of anthropogenic global warming. "Anybody that is a global warming denier at this point in time has got their head so deeply up their a** I'm not sure they could hear me," Cameron added.

As for Beck, "he's a f****** a**hole," the 2010 Oscar nominee so eloquently put it. He backtracked a bit, but still maintained that the FNC host is "dangerous because his ideas are poisonous," echoing a statement by NPR's Cokie Roberts yesterday. "Of course he wound up on Fox News, which is where he belongs, I guess."The Hollywood Reporter reported today:

Asked what he thought about Beck during a junket appearance in support of the "Avatar" home video release, Cameron said: "Glenn Beck is a f****** a**hole. I've met him. He called me the anti-Christ, and not about 'Avatar.' He hadn't even seen 'Avatar' yet. I don't know if he has seen it."

Cameron was apparently referring to Beck's reaction to his 2007 documentary, "The Lost Tomb of Jesus," which casts doubt on the resurrection of Jesus Christ and makes the case that the ancient "Tomb of the Ten Ossuaries" belonged to Jesus' family.

After blasting Beck, Cameron, surrounded by journalists inside a West Hollywood hillside mansion, seemed to reconsider: "I think, you know what, he may or may not be an a**hole, but he certainly is dangerous, and I'd love to have a dialogue with him."...

"He's dangerous because his ideas are poisonous," Cameron answered. "I couldn't believe when he was on CNN. I thought, what happened to CNN? Who is this guy? Who is this madman? And then of course he wound up on Fox News, which is where he belongs, I guess."...

The "Avatar" director was equally unsparing in his comments about those who don't accept global warming as fact.

"That's right," Cameron said. "I want to call those deniers out into the street at high noon and shoot it out with those boneheads."

Turning more serious, he added: "Anybody that is a global warming denier at this point in time has got their head so deeply up their a** I'm not sure they could hear me."
